+# Opentelemetry Auto Instrumentation
+
+The `opentelemetry-auto-instrumentation` gem provides an easy way to load and initialize opentelemetry-ruby for auto instrumentation.
+
+## What is OpenTelemetry?
+
+OpenTelemetry is an open source observability framework, providing a general-purpose API, SDK, and related tools required for the instrumentation of cloud-native software, frameworks, and libraries.
+
+OpenTelemetry provides a single set of APIs, libraries, agents, and collector services to capture distributed traces and metrics from your application. You can analyze them using Prometheus, Jaeger, and other observability tools.
+
+## How does this gem fit in?
+
+The `opentelemetry-auto-instrumentation` gem provides an easy way to load and initialize the OpenTelemetry Ruby SDK without changing your code initialize the SDK. This gem is particularly used with the [OpenTelemetry Operator][opentelemetry-operator].
+
+## How do I get started?
+
+It's recommended to install this gem through `gem install` rather than Bundler since it doesn't require modifying your codebase (including the Gemfile).
+
+Install the gem using:
+
+```console
+gem install opentelemetry-auto-instrumentation
+```
+
+Installing opentelemetry-auto-instrumentation will automatically install following gems:
+```console
+opentelemetry-sdk
+opentelemetry-api
+opentelemetry-instrumentation-all
+opentelemetry-exporter-otlp
+opentelemetry-helpers-mysql
+opentelemetry-helpers-sql-obfuscation
+opentelemetry-resource-detector-google_cloud_platform
+opentelemetry-resource-detector-azure
+opentelemetry-resource-detector-container
+opentelemetry-resource-detector-aws
+```
+
+### Example installation strategies
+
+Instrument your application:
+
+```console
+RUBYOPT="-r opentelemetry-auto-instrumentation" ruby application.rb
+```
+
+Instrument your application with additional environment variables:
+
+```console
+export OTEL_TRACES_EXPORTER="otlp"
+export OTEL_EXPORTER_OTLP_ENDPOINT="your-endpoint"
+export OTEL_RUBY_RESOURCE_DETECTORS="container"
+export OTEL_SERVICE_NAME="your-service-name"
+
+RUBYOPT="-r opentelemetry-auto-instrumentation" ruby application.rb
+```
+
+Instrument your application with disabling certain instrumentation (e.g. sinatra):
+
+```console
+export OTEL_RUBY_INSTRUMENTATION_SINATRA_ENABLED='false'
+RUBYOPT="-r opentelemetry-auto-instrumentation" ruby application.rb
+```
+
+Instrument your application with only certain instrumentation installed (e.g. mysql, redis):
+
+```console
+export OTEL_RUBY_ENABLED_INSTRUMENTATIONS='mysql2,redis'
+RUBYOPT="-r opentelemetry-auto-instrumentation" ruby application.rb
+```
+
+Instrument your application with only redis and configure its options:
+
+```console
+export OTEL_RUBY_ENABLED_INSTRUMENTATIONS='redis'
+export OTEL_RUBY_INSTRUMENTATION_REDIS_CONFIG_OPTS='peer_service=new_service;db_statement=omit'
+RUBYOPT="-r opentelemetry-auto-instrumentation" ruby application.rb
+```
+
+Instrument Rails application:
+
+```console
+RUBYOPT="-r opentelemetry-auto-instrumentation" rails server
+```
+
+Instrument Rails application with `bundle exec`:
+
+Since the `opentelemetry-auto-instrumentation` gem should be installed through `gem install`, anything related to the OpenTelemetry gem won't be stored in Bundler's gem path. Therefore, users need to add an additional gem path that contains these gems prior to initialization.
+
+```console
+RUBYOPT="-r {PUT YOUR GEM PATH}/gems/opentelemetry-auto-instrumentation-0.1.0/lib/opentelemetry-auto-instrumentation" bundle exec rails server
+```
+
+Instrument Sinatra application with rackup:
+
+If you are using a Gemfile to install the required gems but without `Bundler.require`, set `REQUIRE_BUNDLER` to true. This way, `opentelemetry-auto-instrumentation` will call `Bundler.require` to initialize the required gems prior to SDK initialization.
+
+```console
+export REQUIRE_BUNDLER=true
+RUBYOPT="-r opentelemetry-auto-instrumentation" rackup config.ru
+```
+
+If you wish to load some gems outside the Gemfile, then they need to be placed in front of opentelemetry-auto-instrumentation:
+
+```console
+export BUNDLE_WITHOUT=development,test
+gem install mysql2
+RUBYOPT="-r mysql2 -r opentelemetry-auto-instrumentation" ruby application.rb
+```
+
+## Example
+
+In example folder, executing the following commands should result in trace output.
+
+```console
+# if the user doesn't want to install opentelemetry-auto-instrumentation from rubygems.org
+# the user can build the gem and install it with gem install *.gem
+
+gem install opentelemetry-auto-instrumentation
+bundle install
+OTEL_RUBY_REQUIRE_BUNDLER=true  OTEL_TRACES_EXPORTER=console RUBYOPT="-r opentelemetry-auto-instrumentation" OTEL_RUBY_AUTO_INSTRUMENTATION_DEBUG=false OTEL_RUBY_OPERATOR=false ruby app.rb
+```
+
+## Configuration
+
+These environment variables are not standard OpenTelemetry environment variables; they are only feature flags for this gem.
+
+| Environment Variable | Description | Default | Example |
+|----------------------|-------------|---------|---------|
+| `OTEL_RUBY_REQUIRE_BUNDLER` | Set to `true` if you are using Bundler to install gems but without `Bundler.require` in your script during initialization. | nil | N/A |
+| `OTEL_RUBY_ADDITIONAL_GEM_PATH` | Intended to be used for the OpenTelemetry Operator environment if you install `opentelemetry-auto-instrumentation` to a customized path. | nil | N/A |
+| `OTEL_RUBY_OPERATOR` | Set to `true` to set the binding path for the OpenTelemetry Operator. | `/otel-auto-instrumentation-ruby` | N/A |
+| `OTEL_RUBY_RESOURCE_DETECTORS` | Determine what kind of resource detector is needed. Currently supports `container`, `azure`, and `google_cloud_platform`. Use commas to separate multiple detectors. | nil | `container,azure` |
+| `OTEL_RUBY_ENABLED_INSTRUMENTATIONS` | Configuration used when you only want to install instrumentation for specific libraries. | nil | `redis,active_record` |
+| `OTEL_RUBY_AUTO_INSTRUMENTATION_DEBUG` | Set to `true` if want to see some debug information. This to avoid preloading the logger gem | nil | N/A |
+| `OTEL_RUBY_UNLOAD_LIBRARY` | Use OTEL_RUBY_UNLOAD_LIBRARY to avoid certain gem preload (esp. google protobuf) | nil | N/A |
+
+## How can I get involved?
+
+The `opentelemetry-auto-instrumentation` gem source is on GitHub, along with related gems.
+
+The OpenTelemetry Ruby gems are maintained by the OpenTelemetry Ruby special interest group (SIG). You can get involved by joining us on our [GitHub Discussions][discussions-url], [Slack Channel][slack-channel] or attending our weekly meeting. See the [meeting calendar][community-meetings] for dates and times. For more information on this and other language SIGs, see the OpenTelemetry [community page][ruby-sig].

+# Example
+
+## Installation
+
+Install opentelemetry-auto-instrumentation through `gem install`
+Then `bundle install`
+
+
+## Simple Example (simple-example)
+
+```bash
+OTEL_RUBY_REQUIRE_BUNDLER=true  OTEL_TRACES_EXPORTER=console RUBYOPT="-r opentelemetry-auto-instrumentation" OTEL_RUBY_OPERATOR=false ruby app.rb
+```
+
+## Rails Example (rails-example)
+
+Without auto-instrumentation
+```bash
+bundle exec rackup config.ru
+```
+
+In other terminal make the request call
+```bash
+wget http://localhost:9292
+# or curl http://localhost:9292 if you have curl on system
+```
+
+With auto-instrumentation
+```bash
+OTEL_RUBY_REQUIRE_BUNDLER=false  OTEL_TRACES_EXPORTER=console RUBYOPT="-r opentelemetry-auto-instrumentation" OTEL_RUBY_OPERATOR=false bundle exec rackup config.ru
+```
+
+The load sequence must be opentelemetry-auto-instrumentation -> user library -> bundler.require (initialize otel sdk and instrumentation installation)
+
+In other terminal make the request call
+```bash
+wget http://localhost:9292
+# or curl http://localhost:9292 if you have curl on system
+```
